I don't see how "IVs" contribute for the "vision of the game" the creators have. It's an awful mechanic, actually kind of detrimental for the game.
Because you just see the hindrance it has on the current competitive scene. The idea of it is to create variation in Pokémon stats to encourage trades and stop each wild Pokémon being identical
I really hope we get Manaphy and potentially a western release of Shaymin before the next gen comes around.
I continually hope for a new Ranger game, much more than a Dungeon title.
